the distal part of second segment is produced into three pro-

In the male the body is 4.4 mm. long, second leg 7 mm.; 

 in the female the body is 4.7 mm. long, second leg 6.9 mm. 



Remarks. — C. crassipalpe is easily separated from the 

 other species hitherto known of the genus in having the bod\- 

 and most of the legs covered with very broad scales, which are 

 not much longer than Inroad or almost as broad as long. 



Occurrence. — Island of Fernando Poo, at two places: 

 Musola, altitude 400—500 m., Januar}- 1902, 2 males, 3 females,

A. Adult Female. 



Closely allied to C. Ajzclii Thorell as described by Hansen 

 and Sorensen, so that it ma\ be advisable to lay special stress 

 on the differences. 



Cephalothorax slightly longer than broad. Its surface is 

 adorned with numerous moderately large granules conspi-

 outline is circular, the upper surface ver\' moderately arched, 

 marked off from the sides by a sharp outline, very finely stria-

 the; sides of the granules are greyish; between the granules a 

 number of feebly clavate hairs somewhat or considerably lon-
